Title: Driving system by solar battery
IPC: H02M7/48
Filed: 1991-03-29
Abstract: PURPOSE:To effectively utilize the output of a solar battery to the maximum by a simple control mechanism by performing frequency control so as to keep a ratio of difference between the output of the solar battery and a prescribed voltage to an inverter AC output frequency constant. CONSTITUTION:A frequency can be found by picking up the output voltage of the solar battery 1 by potentiometers R1, R2, and performing computation by a linear transformation computing element 2. Such frequency is inputted to a variable frequency control inverter 3 as a frequency command value, and a three-phase induction motor 4 and a pump 5 are driven by three-phase AC output from the inverter 3. In such a case, the frequency control is performed so as to keep a ratio of the difference of the output voltage of the solar battery and the prescribed voltage to the inverter AC output frequency constant, and the prescribed voltage is set at a value in which a voltage that becomes the maximum power in the maximum daylight time is multiplied by a constant (k)(0.7>k>1). Thereby, when the output of the solar battery is increased by increasing daylight, the inverter output frequency is increased, and power consumption is increased. which increases the consumption of the solar battery, thereby, the output of the solar battery can be effectively used.

Abstract: PURPOSE:To increase the efficiency of the pressure encapsuration by superposing and providing both a plastic ceramics gasket and a specified ring-like metallic gasket enriched in the rigidity between the slanted faces appropriate to the punches and a cylinder. CONSTITUTION:The clearances S are caused between the punches 1, 2, the plastic gaskets 10 and the metallic gaskets 11 in a point of time when the upper and lower punches 1, 2 are brought into contact with an inside sample and the inner pressure is started to rise.

Filed: 1992-03-25
Abstract: PURPOSE:To economically form the ridge-type three-dimensional waveguide of a low propagation loss by utilizing a large increase in the etching rate ratio of the positive polarization surface and negative polarization surface of a monopolarized dielectric substance. CONSTITUTION:A pattern is formed by using a conductive thin film 3 on a two-dimensional waveguide 2 consisting of the monopolarized dielectric material and is subjected to a heat treatment to invert a part of the polarization direction of the monopolarized dielectric substance. The ridge shape is formed by chemical wet etching. The pattern is otherwise formed by using the conductive thin film on the monopolarized dielectric material and is subjected to the heat treatment to invert a part of the polarization direction of the monopolarized dielectric substance. The ridge shape is then formed by the chemical wet etching to form the optical waveguide in at least a part on the dielectric material. No influence is exerted on the crystal structure according to the polarization inversion method, like Ti diffusion and proton exchange, in such a case, and therefore, the waveguide having excellent optical characteristics are produced.

Abstract: PURPOSE:To improve the transfer efficiency of signal charge by forming a storage electrode of a resistive material, and giving the storage electrode a difference in potential in such a way that a well of a potential under the storage electrode becomes deep on a transfer gate side. CONSTITUTION:On a semiconductor substrate 9, a photodiode 1, a storage electrode 3, a transfer gate 4, and a transfer electrode 6 of a CCD are formed. The storage electrode 3 is formed of a resistive material such as polysilicon, and a terminal edge Z1 on the side of the photodiode 1 and a terminal edge Z2 of the side of a transfer gate 4 are provided with terminals 27a and 27b respectively.
